    run a can of Seafoam! and then do the intake treatment as well.. That really will help the most. There are a bunch of threads on the site that talk about seafoam and its benefits!

    x2 on the SEAFOAM when added to the fuel tank, and cleaning the throttle body & intake... their entire line of products has never caused me any problems (with seals, gaskets, o-rings. etc.).

    x3 on the Seafoam! Put a full can in your gas tank - you'll be glad you did!

    Are automobile manufacturers advocating the use of fuel and engine additives for their products? There is a wise old adage. "If it ain't broke don't fix it". I realize people have an innate compulsion to tinker with and screw around with things and have always been tempted by magical elixirs. Octane boosters, oil additives, fuel additives etc....Me, I don't spend my $$$ on fuel or engine additives or the myriad of products and snake oils out there that claim to do this or that unless the manufacturer recommends a products use. If there were additives that worked wonders I am sure every engine manufacturer would recommend them. But to each his own.

    The FIRST place I ever saw Seafoam for sale was at a GM stealership...It was THE recommended top end cleaner they sold in the 80's...

    One good thing about the the better additives ( Seafoam ) is that it will remove any water that has formed in your gas tank from condensation. Since your trucks been sitting for 10 months I would add Seafoam to the gas tank, take off the throttlebody and clean both sides with a spray throttlebody cleaner like CRC or Seafoam t/body cleaner and a old soft toothbrush, as I've said before on this site DON'T use carb cleaner. I would also use the Seafoam spray to clean inside the intake maniflod. If you go to Seafoam.com its shows how to use there products.

    I think that I understand from whence you are coming. But there are times when additives are necessary (and/or useful). One example, just mentioned here, is "water in the fuel".

    Ethanol (matters not whether it's 10% or 85%) contains alcohol... and alcohol attracts moisture... which can eventually lead to "product separation". It is that moisture/water which can corrode/damage metal parts. So using SEAFOAM, not only as a "cleaner" but also to mitigate "water in the fuel" makes sense. Some experts say that fuel (ethanol especially) can degrade within a matter of 90 days.

    There's also the problem of moisture in the OIL... each time there's a TEMP change/difference between the AIR and interior engine... condensation forms. Typically, it gets burned off / evaporates when the engine heats up... but many "short trips" (with cooling in between them) can degrade engine lubrication... so a little SEAFOAM is useful there as well (depending on one's driving habits).

    Then too, there's the matter of buying a USED vehicle. For example; I bought my '04 Silverado and also my wife's '00 Buick Century "used". Her Century exhibited "noisy lifters"... when started, until the engine completely warmed-up. I attributed such behavior to "sticky" lifters. So, I changed the OIL and added SEAFOAM... within 500 miles of driving, there was no longer any "noise" from the lifters (even in the dead cold of winter).

    Also there are additives for the coolant system. GM dealers even use "stop leak pellets" (made by BARS, IIRC)... to address minor seepage issues.

    But, back to your point:

    I would not go about experimenting with "additives" just for the hell of it... I always try to determine if there's a need for same.

    ...the above is just my 2cents, YMMV

    I never thought about the intake side..I work at Wal mart Tire&lube an we do a similar service with gum-out(gum-in lol).I plan to do this with the Seafoam ASAP.The FAQ on there website was very informative..if i read right seafoam says to add 1oz to gas per gallon..So since i got a 42gallon tank i need 3 cans correct?I figure 3 cans will give me my 40 to 42oz i need for the tank an my 1/2 can to use in the brake booster line?What do yall think?
    Being its cold out do you think it would be ok to wait a few months to do the cleaning of the TB?I have to do all my work outside/..

    Thanks for all the tips everyone i really do appreciate it

    As a side note, perhaps of interest to all... there's this (regarding ETHANOL FUELS), from the FAQ located on the hyundai.com.au website:

    Use of Ethanol in cars & trucks is not normally a problem (when they don't SIT, unused, for too very long). It typically presents a problem in small engines (both two and four cycle) and GAS CANS used for same... which may sit unused for several months at a time. A friend owns a lawn & garden sales & service center... every SPRING he makes a killing (because people do NOT properly store their lawnmowers, trimmers, blowers, chainsaws, etc.).

    I put less than 5000 miles/year on my truck, wifey less than 7000/year on her car. As I've mentioned before, both vehicles get SEAFOAM treatment (in the gas tank and in the oil). Doing this has not caused any problems for me, over the years...

    Yeah it is fine.. i know the feeling of cold.. I had to replace the radiator yesterday in -6 weather... Stupid 50/50 premix. Froze up...

    As to the amount for your gas tank. i would just go with one can and then a can or two of HEAT... that will do the most, and since you plan to treat the intake with it that will also clean the injectors out ets with out to much fretting..
    BE sure that you replace the fuel filter in the spring, and also since it has been sitting it would be a very very good idea to replace the Cap and rotor. Those corrode so fast on these trucks even when they are being used daily.

    Funny us say that...I was having charging problems an thought that the miss it had while running etc was due to the alternator an battery..I changed them..An it still had a miss.I decided to have the ignition control module tested.When i pulled the cap it nor the rotor looked very good..The I.C module tested bad.,.So i got it a cap an rotor..An the miss went away..I plan to replace wires an plugs in the next few months..

    Oh and another thing to put on the list is a TBI rebuild kit or at least pull the TBI off and clean it really really well with TB cleaner. Make sure you replace the base gasket below the TB when you do...
